Definition of cardiac cycle time intervals. The different cardiac cycle time intervals are displayed at the top. a A myocardial velocity trace analyzed with the automated algorithm. b A myocardial velocity trace analyzed manually. c An acceleration trace where shifts have been identified manually in order to define cardiac cycle time intervals. d Estimated opening and closure of mitral valve (MO/MC) and aortic valve (AO/AC). e Estimated ECG reading indicating the likely position of P, Q, R and T wave
